SATELLITE ANALYSIS AND TRENDS...MERGER OR INFUSION OF PINAL COUNTY CELL
INTO COLD TOP CONVECTION MOVING THRU E PIMA COUNTY HAS RESULTING IN
COOLING/EXPANDING CLOUD TOPS TO -73C...WHICH NOT TOO USUAL FOR ARIZONA
EVEN IN THE SUMMER TIME.  PW MOISTURE ONLY MODERATE AND THIS INHIBITING
MAX EFFICIENCY OF RAINFALL PRODUCT...BUT MERGE AND ANY PERSISTENCE FOR
MORE THAN ONE HR WILL MAKE UP FOR ANY DIFFICIENCIES AND EXPECT THAT TO
HAPPEN AS PW GRADIENT SHARPENING AS STORM EDGES SLOWLY WEST INTO CENTRAL
PIMA COUNTY CLOSE TO AREAS THAT GOT HVY RAIN YESTERDAY.  SO IF THESE
STORMS CAN PERSIST THRU 05Z...LOOKING AT MAX RAIN RATES OF UP TO 1.3".
IF STORMS KEEP MOVING INTO W PART OF PIMA...THEY WILL SLOWLY WEAKEN WITH
RAINFALL DECREASING...BUT NOT SURE THAT WILL QUITE HAPPEN TILL AFTER 06Z.
WILL CONTINUE TO MONITOR...
